Evolutionary equilibrium of labile plasticity in a quantitative character in a biperiodic environment. All panels have the same parameters for the environment and the components of plasticity in a character (Table 1). Insets show the norms of reaction of the components and the mean phenotype. (A) The character has only one component of plasticity, either component 1 alone or component 2 alone (Eqs. 1c and 1d). Subsequent panels have two components of net plasticity in the character, with different patterns of developmental integration. (B) No integration (Eqs. 4). (C) Serial integration (Eqs. 5). (D) Reverse serial integration. (E) Complete integration (Eqs. 6). (F) Negative serial integration (Eqs. 5). (G) Negative reverse serial integration. (H) Negative complete integration (Eqs. 7). For complete and negative complete integration, E and H, Insets show observable reaction norms in the Table 1 footnotes.
